Maintenance
Chapter8
Do not operate the fan with the safety protections removed: safety meshes can be
removed only with specific tools by qualified technicians when the fan reaches a
complete standstill.
The fixing sytems of the safety protections are not interchangeable with other
devices. Therefore, if for maintenance reasons the user damages or loses any
component, this must be definetely ordered from the manufacturer as spare
parts and it cannot just be replaced with other components, even similar, not
supplied by the constructor itself. In this particular event the manufacturer refuses
all responsibility on consequent damages caused to things and people and
considers any kind of warranty lost.
